AMD’s Zen 5 “Turin” CPUs Leak: Zen 5c Boasts 192 Cores, 384 Threads

Rumors surrounding AMD’s upcoming Zen 5 processors have started to circulate, giving enthusiasts a glimpse into what the future holds for the company’s CPU lineup. According to leaked information from YuuKi_AnS, the EPYC Turin server CPUs are expected to make their debut in late 2024, boasting impressive core counts and thread numbers.

The Zen 5c variants of the Epyc Turin CPUs are set to dominate the cloud-centric market with their staggering 192 cores and 384 threads. This is a significant increase from the previous Zen 4c-based Bergamo, which featured 128 cores and 256 threads. The mainstream P-core platform will also see a boost, reaching a maximum of 128 Zen 5 cores and 256 threads, up from 96 on the Zen 4-based Genoa.

One of the highlights of the Zen 5 architecture is the 128-core Epyc Turin CPU, codenamed “Nirvana.” This powerful processor combines up to sixteen 8-core CCDs (Core Complex Dies) with 32MB of L3 cache, along with an I/O die that supports DDR5-6000 memory and Infinity Fabric Gen 3. The Epyc Turin CPUs also offer support for PCIe Gen 5 and CXL 2.0 bus protocols, making them compatible with the latest technologies. Additionally, these processors come equipped with an integrated secure processor for enhanced security measures.

For cloud-focused applications, the Zen 5c variant, codenamed “Prometheus,” takes center stage. Featuring twelve Zen 5c CCDs, each housing 16 cores and 32MB of L3 cache, this variant offers an astounding total of 192 cores and 384 threads. With 384MB of L3 cache and an I/O die shared with the Turin family, the Zen 5c CPUs are poised to deliver exceptional performance in cloud computing scenarios. Furthermore, AMD plans to leverage TSMC’s N3 (3nm) process node for these processors, ensuring improved performance and efficiency.

While specific details about the Zen 5 lineup are still scarce, @Ditto_55 has confirmed several Epyc Turin “Zen 5” processors. These include the AMD BREITHORN with 128 cores and 16+1 configuration, the 96-core 12+1 variant, the 64-core 8+1 model, and the wide version of the 64-core 8+1 CPU.

AMD enthusiasts can expect the Epyc Turin processors to hit the market in the second half of 2024. With a restructured front-end, faster core interconnect, and higher clock frequencies compared to its predecessor Zen 4, Zen 5 promises to be a significant upgrade. Intel’s Granite Rapids-SP will likely be its main competitor, while Sierra Forest and Clearwater Forest are expected to go head-to-head with the Zen 5c variant.

As we eagerly await the arrival of AMD’s Zen 5 “Turin” CPUs, it’s clear that the company is pushing boundaries and aiming to deliver unparalleled performance and efficiency in the world of server processors. With impressive core counts, enhanced architecture, and support for technologies, these CPUs have the potential to revolutionize the industry once again.
